For production use at least one dedicated MySQL server
is required, with enough memory to cache most the records. For
storing approximately 25 ensembles per day of 10,000 tests each
with 100,000 coverage bins you'll need around 16GB of memory.

You'll also need one or more memcached servers, with enough total
memory to hold the data currently being aggregated. Using the example
above you'll need around 8GB.

For source annotations, a version control system web frontend
is required. A plugin for Subversion with Viewcvs is included,
but it's easy to write others.
